A baktun is a unit of time in the Mayan Long Count calendar, equivalent to 144,000 days or roughly 394.3 years. This system was developed by the ancient Maya to track long periods of time, allowing them to record historical events and important dates across centuries. The baktun is part of a larger cycle that includes various units, such as tun, uinal, and k'in, creating a complex framework for understanding their chronological history.
